As a source of events, the work is of limited value due to its chronological and geographic inadequacy, but it is of significant historical value, as it has helped shape our understanding of the 10th century and the moral and cultural condition of Europe at the end of the so-called "Dark Ages", and the turning of the first millennium.
Historiarum was first published in 1596 from a manuscript owned by Pierre Pithou, as part of a collection of eleven medieval chronicles.
